Struct StringRecord 

pub struct StringRecord {
    pub is_atom: bool,
    pub keep: AtomKeep,
    pub array_index: u32,
    /* private fields */
}

Fields

is_atom: bool

keep: AtomKeep

What keeps an atom alive besides its holders.

array_index: u32

For atoms spelling an array index too large for an immediate PropertyKey: that index, else NONE.

Implementations

impl StringRecord

pub fn new(repr: StringRepr) -> Self

pub fn rope(len: u32, one_byte: bool) -> Self

A rope len units long; the heap records its halves.

pub fn repr(&self) -> &StringRepr

The units. A rope reached through super::Heap::string is flat.

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn is_one_byte(&self) -> bool

pub fn hash(&self) -> u32

fn vacant() -> Self

The poison value written over a freed slot. It must own no heap memory.

fn extra_bytes(&self) -> usize
